IMPROVEMENT IN SEAT-FRAME FOR VEHICLE.

Specification forming part of Letters Patent No. 103,024, dated May 17,1870.

To all whom 'it may concern:

Be it known that I, JESSE W. DANN, of Columbus, in the county ofFranklin and State ot' Ohio, have invented a new and Improved Mode ofConstructing Seat-Frames for Vehicles; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing'had to the accompanyin g drawings making part of thisspecification, in which- Figure l is a section view of a buggy, showingthe improved seat-frame applied to it. Figs. 2, 3, 4, and 5 aredifferent views, showing the manner-of uniting the frame and seatboard.

Similar letters of reference indicate corresponding parts inV theseveral figures.

rIhe object of this invention is to improve the seat-frames of vehiclesby uniting VHthese frames together in such a manner'thatinterlockingjoints are formed, which will render unnecessary the use of nails tohold the pieces together, at the same time providing for firmlysecuringtheseat-boards into theframes, as will be hereinafter explained.

To enable others skilled in the art to understand my invention, I willexplain its construction and operation.

One of the usual modes of constructing seatframes or seat-bottoms forlight vehicles is to halve and nail together the ends of theframepieces, and then nail the seat-boards into rabbets made into theinner edges ot the frameadopted, is not only expensive, but the framesand seat-boards thus put together soon give way at the joints inconsequence of the swellingl and contraction of the Wood, and the roughusage to which the frames are necessarily exposed. v

I construct the seat-frames or seat-bottoms in the following manner: The-frame A is rectangular when iinished, and is composed of twolongitudinal pieces, a a, and two transverse end pieces, b b, securedtogether at their ends, and inclosing a seat-board, B. The

This mode, as well as others hitherto` The stuft for the transverseorrend pieces b is run through a machine suitably adapted to Y thepurpose, and beveled at the upper halt' of its inner edge, as shown ate, Figs. 4 and 5.

The stuff thus prepared lis cut in proper lengths and halved togetherand glued at the ends. In halving the ends V-shaped grooves are made at11 z' for receiving the beveled edges of thecontiguous pieces, as shownin Fig. 5. In putting together the four parts constituting the frame A,I arrange these pieces around the seat-board B, the edges ot'which arebeveled to correspond with the beveled edges of the contiguous pieces,thereby coniining the seat-board permanently in place at the same timethat the frame is completed.

It will be seen from the above description that the ends of theframe-pieces are halved and locked together, so that they can besubstantially secured in place by means of glue; also that thelongitudinal edges oi'l the seatboard B are fitted beneath theoverhanging portions ot' the corresponding edges ot' the longitudinalpieces a ain the V-shaped grooves. Thus no nails are required to securethe seatboard in place in the frame, and this board cannot work loose aslong as the frame-pieces hold together.

Having described my invention, what I claim as a new article ofmanufacture is v A seat-frame or seat-bottom, constructed substantiallyas described.

JESSE W. DANN.
